While the company has seen a rally in its own stock price today, up 26 percent on the day to $3.27 per share as of this writing, other mutual fund giants, including Vanguard Group and Fidelity Investments, said they were refusing to route trades to Knight.

Reuters reported that the mood outside the company’s offices in Jersey City, New Jersey is "dour," with police officers stationed outside the entrance.

One Knight staffer was seen carrying a set of golf clubs near the building, and told a Reuters reporter: "I don’t want to care [how things are going.]"

However, if there’s any silver lining in the entire fiasco for Knight, it's that Fitch Ratings described the situation Friday as "manageable."

"The large trading losses suffered by Knight Capital Group (KCG) since Wednesday's software glitch may ultimately lead to a structural change in the equity market-making business, but Fitch Ratings believes exposure to KCG, among large rated counterparties, is moderate and manageable," the ratings agency said in a statement.

"As a result, even in a bankruptcy scenario, we do not expect any major rated institutions to suffer large losses linked to KCG's difficulties."
